They locked me from financing my new account with fiat USD.  I am new to Crypto so i wanted to start slow and get a sense of how the whole transaction process worked before committing larger dollars.  I ACH deposited $2k to my new account no problem and promptly bought crypto with half.  I then ACH deposited $2k more and bought some more BTC.  Went to ACH more fiat and account was locked for 21 days.  Email to support was useless as they would not give any explanation as to why my account was locked.  As the price of BTC rose hyberbolically (Nov 2020), I was prevented from buying more due to the lock on my account.  In the meantime I opened an account on an different exchange with lower conversion rates and emptied my Bitcoin account when they unlocked it, never to use it again.
